According to the study South Africans tweeted over five million messages. Kenya was the next closest with 2 476 800 tweets. The next three countries to round off the top five were Nigeria (1 646 212), Egypt (1 214 062) and Morocco (745 620).

The study analysed over 11.5 million geo-located tweets originating on the continent and a survey of the 500 most active African tweeters. South Africa's result as the number one tweeting nation in Africa is a bit of surprise if you look at the Internet penetration in South Africa compared to other African countries.

South Africa surprisingly has a very low Internet penetration due to a number of reasons from its geographic location all the way to down to poor planning but thankfully it is slowly changing and the African powerhouse is getting back on track. So why is South Africa tops when Internet access is limited?

The answer presumably lies in the fact that 57% of the tweets were sent from mobile devices. South Africa has cellular coverage of something like 99% of the country. This means anyone with a mobile device capable of tweeting is accessible to the almost 43 million cellular enabled market in South Africa.

"One of the more surprising findings of this research is that more public figures have not joined Africa's burgeoning Twittersphere," said Mark Flanagan, Portland's partner for digital communications.

"With some notable exceptions, we found that business and political leaders were largely absent from the debates playing out on Twitter across the continent."

The seemingly large absence of political leaders on Twitter in Africa is interesting as most 60% of the users are aged between 20-29 years old. We have seen the world over how the correct use of Twitter can make a leaders campaign a success or failure.

"We saw the pivotal role of Twitter in the events in North Africa last year, but
it is clear that Africa's Twitter revolution is really just beginning," said
Beatrice Karanja, associate director and head of Portland Nairobi in
Kenya.

"Twitter is helping Africa and Africans to connect in new ways and
swap information and views. And for Africa, as for the rest of the world, that
can only be good."
